Abstract
In a glass tempering system (11) a blow back control device (10) disclosed includes a housing (24) having a pair of housing portions (34) defining a pair of suction chambers (26) mounted above an exit opening (20) of a glass heating furnace (12). Housing (24) has a slot (32) including slot portions (36) extending along and opening into suction chambers (26). Blowers (30) are connected to each suction chamber (26) for drawing spent cooling gas into suction chambers (26) through slot portions (36) and for discharging the gas away from exit opening (20) of furnace (12) to avoid temperature swings in the furnace caused by cooling gas entering the furnace.
